At the end of the sneak pass during Friday's practice, Blue Angel #5 exits almost directly overhead. Even though the jet was a few tenths under the magic Mach 1.0, the acceleration of the turn caused a small boom to just barely be heard and felt.

  • I can go into a long explaination of the physics involved but basically a mini boom results because air flowing over any curved surface has to accelerate. So even if the jet is flying at Mach 0.9, there are parts of it that are experiencing supersonic flow (thats why airliners use supercritical wings to delay the drag buildup). Addiditional acceleration from hard turns can further compress those local areas of flow to make a mini-boom. Theres more invovled but if anyone has questions, fire away!

  • love hearin that just before he passes.

  • This is a nice clip. Good video and captures the aircraft at a perfect moment. Thanks.

  • @SemperApollo nerd, but quite correct. I guess that makes me a nerd to know you were correct : D

  • @SemperApollo can u explain the part about airliner wings again? were you talking about why they curve up at the tips? ive always wonderd about that.

  • @SemperApollo

    Even since Concords retirement, you can still find Mach 1 on commerical airliners such as the Jumbo 747 or 777's. This is partly due to tailwinds.

  • @ semperapollo, thanks for the info. That was friggin' COOL!!!!!!!

  • Everybody shut the fuck up you dumb "youtube geniuses" I think the most logical explanation is said by the up loader himself.

  • Im Glad you know whats goin on Chris cuz there's a lot of people out there on youtube who know way more then we do. pahahaha!

  • love it
